IL-27
IL-27 (Interleukin-27) is a heterodimeric cytokine of the IL-12 family, composed of two subunits, EBI3 (Epstein-Barr-virus-induced molecule 3) and p28[1]. IL-27 enhances the development, proliferation, and cytotoxic activity of CD8+ T cells, thereby indirectly promoting anti-tumor immunity. IL-27 shows pro- and anti-inflammatory, suppresses T-cell proliferation, stimulates cytotoxic T-cell activity, induces isotype switching in B-cells, particularly with regards to inhibition of Th2, Th17 and Treg differentiation, and that has diverse effects on innate immune cells[2]. IL-27 activates STAT1, STAT3, STAT6, ERK and p38 MAPKs, and Akt, resulting in enhanced cell proliferation[3]. IL-27 drives rapid clonal expansion of naive but not memory CD4 T-cells. It also strongly synergizes with IL-12 to trigger interferon-gamma/IFN-gamma production of naive CD4 T-cells, binds to the cytokine receptor WSX-1/TCCR[4].

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
